General Information about RF800LW self-cleaning basket strainers

RF800LW filters are general purpose suction intake basket strainers with a built-in self-cleaning mechanism that back-washes their mesh as your pump draws water. These are all stainless steel, high volume screens developed specifically to meet the challenges of EPA and Environnment Agency regulations for raw water abstraction.  

The designation RF800LW indicates that the filter body has stretched mesh under tension as its body rather than a basket cage.  This gives exceptional open area to the screen allowing more flow for the basket area. Dirty water is screened at source, helping to prevent the intake, pump and any connected equipment from blocking. 

These 950 mm diameter self-cleaning intakes attach to the suction of surface mounted pumps. Here are some typical uses of these filters:

  • Irrigation and livestock watering
  • Cooling water screening for EPA Rule 316 (b) and Eel Regulations compliance
  • Filtration for spray bars and fountains
  • Screening industrial process water
  • Screening water when draining / flooding wetlands
  • Protecting district wide heat pump installations
  • Screening for desalination plant intakes
RF800LW Optimised

RF800-600LWs assembled ready for testing

Rotorflush RF800LW self-cleaning suction intakes can be fitted with:

316 stainless Woven Mesh

A coarse woven mesh screen providing low maintenance cycles, filters and screens with coarse mesh come fitted with rubber backwash jets which are suitable for handling larger particles. Ideal difficult water conditions.

Mesh apertures available: 1 mm, 2 mm, 3 mm and 5 mm mesh or contact us if you have a particular requirement.

RF800LW self-cleaning basket strainers are ideal for screening and pumping raw water, cooling water, and sea water, particularly where there is a need to protect aquatic life. Their high volume, low-velocity intake easily complies with EPA and Enviroment Agency rules.

The strainers have a dry weight range from approx. 80kg - 150 kg depending on model and outlet flange size, lifting gear is required to move them. RF800LWs can be suspended in lakes, lagoons or rivers, or floated from buoys, or raised and lowered on a guide-rail system.  They can often be bolted directly on to the intake of vertical and immersible pumps.

For best performance, make sure that there is good clearance around the strainer mesh so that back-washed debris can disperse, and that the RF800LW is above any silt or sludge that may accumulate.

We also manufacture stands and guide rails specifically designed for our products to help you site and maintain them.

Usually very little. Although they are self-cleaning all of our products will require a manual clean every once in a while.

The nylon mesh inserts are easily replaced, and stainless mesh can be cleaned with a pressure washer. How often depends on your mesh size and what you are filtering.

As a minimum we recommend the following:

  • Coarse mesh that is 1 mm or bigger should be inspected and cleaned every 6 - 12 months

Full maintenance guidelines can be found in the instruction manual available from the download link above.

All our products are guaranteed for at least a year.  Full details in our Terms and Conditions.
